the skyline had a split vac line to the gate, stuck it on a dyno and it maxed out the dynos map sensor and my boost gauge. so it was somewhere north of 42 psi, the ECU pulled so much timing and added so much fuel it was shooting droplets of fuel unburnt out the exhaust and all over the wall along with a diesel like black cloud, dropped 100kw too for a mere 290kw run.
